         2 . The wind turbine of  claim 1 , wherein said ring pair assemblies are positioned concentrically on said axle member. 
     
     
         3 . The wind turbine of  claim 2 , wherein said ring pair assemblies are positioned concentrically on said axle member in a single plane. 
     
     
         4 . The wind turbine of  claim 2 , wherein said ring pair assemblies are positioned concentrically on said axle member such that a gap is present between adjacent ring pair assemblies. 
     
     
         5 . The wind turbine of  claim 1 , wherein said stay members extend to said axle member on both sides of said inner and outer ring members. 
     
     
         6 . The wind turbine of  claim 1 , wherein said stay members are composed of cable or wire. 
     
     
         7 . The wind turbine of  claim 1 , wherein said blade members are sheet-like members thin in cross-section. 
     
     
         8 . The wind turbine of  claim 1 , wherein the angle of said blade members relative to a plane containing said ring members is adjustable. 
     
     
         9 . The wind turbine of  claim 8 , wherein the angle of said blade members relative to the plane containing said ring members is adjustable by a remote control system. 
     
     
         10 . A wind turbine comprising:
 a rotor assembly comprising an elongated rotating axle member, a plurality of rotating ring pair assemblies, each said ring pair assembly comprising an inner ring member and an outer ring member joined to each other by a plurality of blade members, and a plurality of stay members connecting said inner and outer ring members to said axle member, wherein said ring pair assemblies are independently mounted on said axle member and said stay members alone are sufficient to maintain the position of said ring pair assemblies relative to said axle member.   
     
     
         11 . The wind turbine of  claim 10 , wherein said ring pair assemblies are positioned concentrically on said axle member. 
     
     
         12 . The wind turbine of  claim 11 , wherein said ring pair assemblies are positioned concentrically on said axle member in a single plane. 
     
     
         13 . The wind turbine of  claim 11 , wherein said ring pair assemblies are positioned concentrically on said axle member such that a gap is present between adjacent ring pair assemblies. 
     
     
         14 . The wind turbine of  claim 10 , wherein said stay members extend to said axle member on both sides of said inner and outer ring members. 
     
     
         15 . The wind turbine of  claim 10 , wherein said stay members are composed of cable or wire. 
     
     
         16 . The wind turbine of  claim 10 , wherein said blade members are sheet-like members thin in cross-section. 
     
     
         17 . The wind turbine of  claim 1 , wherein the angle of said blade members relative to a plane containing said ring members is adjustable. 
     
     
         18 . The wind turbine of  claim 17 , wherein the angle of said blade members relative to the plane containing said ring members is adjustable by a remote control system. 
     
     
         19 . The wind turbine of  claim 10 , further comprising a tower member supporting said rotor assembly. 
     
     
         20 . A wind turbine comprising:
 a rotor assembly comprising an elongated rotating axle member, a plurality of rotating ring pair assemblies positioned concentrically on said axle member such that a gap is present between adjacent ring pair assemblies, each said ring pair assembly comprising an inner ring member and an outer ring member joined to each other by a plurality of blade members, and a plurality of stay members connecting said inner and outer ring members to said axle member, wherein said stay members extend to said axle member on both sides of said inner and outer ring members, and wherein said ring pair assemblies are independently mounted on said axle member and said stay members alone are sufficient to maintain the position of said ring pair assemblies relative to said axle member.
